Power Station 600hp Water Pump Noise Reduction

Power station water pump noise control

These water pumps generated 95 – 99 dB(A) and were the subject of a dispute with the suppliers re the agreed noise levels. Various acoustic barriers and partial enclosures were being considered – at high cost and with considerable access issues. Our detailed vibration analysis proved that the required noise reduction could be achieved simply via constrained layer damping plus laminated close shields. These provided a 12dB(A) noise reduction with no effect on access, operation or maintenance – and at a tiny fraction of the previously proposed costs.

This is an example of the efficacy of accurate diagnosis coupled with good engineering and knowledge of materials. More information is available on the Sound Damped Steel installer website here.
